Shoe structure

ABSTRACT

The present invention relates to a comfortable shoe structure capable of preventing relative displacement between the shoe pad and the shoe, so as to make the walk comfortable. The shoe structure includes: a sole assembly comprising a big sole and a mid sole integrally formed with the big sole; at least a comfortable block fixed between the big shoe and the mid shoe and partially protruded out of the mid shoe; a vamp, a lower edge of which located between the big sole and the mid shoe.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a shoe structure, and more particularly to a comfortable shoe structure.

2. Description of the Prior Arts

To make the people walk more comfortable, the inner sole of a shoe is usually additionally provided with a shoe pad that is soft and used to bear and relieve the pressure from the foot. Since the shoe pad is flat and foot-like member, and the sole of the foot is not flat (a space between the toe and the sole of the foot, and the arch of the foot), the shoe pad is unable to closely abut against the sole of the foot, so it is difficult to make walk comfortable.

As shown in FIG. 1, an improved shoe pad 11 is provided with plural protrusions 12 so as to correspond to the space between the toe and the sole of the foot and the arch of the foot. The shoe pad 11 is set on the inner sole of a shoe, so as to make the shoe pad 11 abut closely against the sole of the foot and to make the walk comfortable. However, this shoe pad still has some disadvantages that need to be improved as follows:

The shoe pad 11 is unable to integrally combined with the shoe 13 since it is replaceably set on the inner sole, so the shoe pad 11 is moveable relative to the shoe 13. When the wearer is walking, the shoe pad 11 will move in the walking direction (the front portion of the shoe 13), such that the shoe pad 11 will be deformed and even folded, thus the protrusions 12 on the shoe pad 11 are unable to be aligned to the concave portion of the foot. Thereby, it will not only make the walk uncomfortable, but also will probably hurt the foot.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional shoe structure.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a comfortable shoe structure capable of preventing relative displacement between the shoe pad and the shoe, so as to make the walk comfortable.

The shoe structure in accordance with one aspect of the present invention includes:

a sole assembly comprising a big sole and a mid sole integrally formed with the big sole;

at least a comfortable block fixed between the big shoe and the mid shoe and partially protruded out of the mid shoe;

a vamp, a lower edge of which located between the big sole and the mid shoe.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 3-6, a shoe structure in accordance with the present invention is shown and generally comprises: a sole assembly 20, two comfortable blocks 30 and a vamp 40.

The sole assembly 20 includes a roughly foot-shaped big sole 21 and a mid sole 22 which is integrally formed with the big sole 21. A through hole 221 is formed on the front end of the mid sole 22, and adjacent to the through hole 221 is formed a gap 222.

The two comfortable blocks 30 includes a resilient member 32 covered with a cloth 31. Each comfortable block 30 is circumferentially formed with extension 33. The comfortable blocks 30 are formed between the big sole 21 and the mid sole 22 and located corresponding to the arch of the foot. The extension 33 of the comfortable block 30 is located at the periphery of the through hole 221 and the periphery of the gap 222 of the mid sole 22. Furthermore, each of the comfortable blocks 30 partially protrudes out of the through hole 221 and the gap 222 of the mid sole 22.

The vamp 40, a lower peripheral edge of which is a clamping portion 41 that is located between the big sole 21 and the mid sole 22. The comfortable block 30 protruding out of the gap 222 of the mid sole 22 is partially adhered to the inner side of the vamp 40. Furthermore, a strengthening portion 42 is formed on the clamping portion 41 and corresponds to the gap 222 of the mid sole 22, so as to enforce the combining force between the vamp 40 and the mid sole 22.

Referring to FIG. 5, since the comfortable blocks 30 is fixed on the sole 20 in a manner that corresponds to the arch of the foot 50 (between the big sole 21 and the mid sole 22), the comfortable blocks 30 are integrally formed with the sole 20 assembly. And due to partially protruding out the mid sole 22, the comfortable blocks 30 are able to abut closely against the arch of the foot for creating a better feeling when walking. Furthermore, the comfortable blocks 30 are fixed on the sole assembly 20 and not integrally combined with the shoe pad, thereby, when the user is walking, slide and displacement of the shoe pad will not cause the displacement of the comfortable blocks 30. Thus, the present invention makes the walk comfortable. Besides, since the partially protrusive comfortable blocks 30 correspond to the arch of the foot, the sole of the foot is allowed to closely combined with the inner sole of the shoe, which makes the walk comfortable when wearing the shoe of the present invention.

It will be noted that, as shown in FIG. 3, the processes for making the shoe are explained as follows: choose a shoe last (not show), on which is predetermined with two grooves, put the mid sole 22 on the shoe last in a manner that the through hole 221 or the gap 222 is aligned to the grooves of the shoe last. And then put the comfortable blocks 30 on the mid sole 22 and making the extension 33 abut against the peripheral edge of the through hole 221 and the gap 222, so that part of the comfortable blocks 30 will insert in the grooves of the shoe last after passing through the through hole 221 and the gap 222. After that, cover the shoe last with the vamp 40 in a manner that the extension 41 abuts against the periphery of the mid sole 22. At this moment, the comfortable blocks 30, the mid sole 22 and the vamp 40 can be integrally assembled to each other through sewing or adhering process, and then to be assembled with the big sole 21. Finally, a comfortable shoe is obtained by taking out the shoe last.

While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
